Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pigment extraction, in particular to a plant pigment extraction equipment for textile production. BACKGROUND

[0002] There are many types of plant pigment extraction equipment for textile production, such as solvent extraction equipment, microwave extraction equipment, ultrasonic extraction equipment, etc. When extracting heat-sensitive plant pigments, the temperature rises rapidly during the heating process of solvent extraction and is not easy to control accurately, which is extremely unfavorable for heat-sensitive plant pigments. It can easily cause the structure of pigments to change, decompose or deteriorate due to excessive temperature, affecting the color, stability and biological activity of pigments. Microwave extraction directly heats the water in plant materials through microwave radiation, causing the pigments and other components inside the cells to be quickly dissolved out. However, microwave heating can cause local overheating, especially when the equipment does not have a good temperature control system. High temperature can cause damage to heat-sensitive pigments, leading to degradation or inactivation of pigments. Ultrasonic extraction uses the cavitation effect of sound waves generated by ultrasonic waves to break the plant cell wall, thereby releasing the effective components inside the plant. It is a physical action that usually takes place at low temperature, avoiding damage to heat-sensitive pigments caused by excessive temperature. Although the overall temperature is relatively low, the energy utilization of ultrasonic waves is low, and the extraction process is relatively slow.

[0003] In view of the problem of slow extraction of heat-sensitive pigments by conventional ultrasonic extraction equipment, the prior art provides some solutions, such as the invention patent with patent application number CN202020592657.2 discloses a plant extraction liquid extraction equipment. The scheme is that the outer extraction tank is provided with a top cover at the bottom, the upper surface of the top cover is provided with an upper handle, the side of the outer extraction tank is provided with a side handle, the other side of the outer extraction tank is provided with a booster tank, the upper end of the booster tank is provided with a pressure gauge, the inside of the outer extraction tank is provided with an inner extraction tank, the bottom of the inner extraction tank is provided with a bottom filter plate, the lower part of the bottom filter plate is provided with a through liquid outlet valve and a liquid inlet valve on the inner extraction tank and the outer extraction tank, a spiral stirring rod is arranged in the extraction tank, the spiral stirring rod can fully stir the extraction liquid and the plant, an ultrasonic generator is arranged in the stirring rod to further stir the extraction liquid uniformly, accelerate the target component into the solvent, and promote the extraction of the plant extraction liquid; but the above scheme still has some problems, the circular bar-shaped ultrasonic generator can theoretically emit ultrasonic waves in the axial direction, but due to the shape, material and surrounding medium of the stirring rod, the ultrasonic waves may be reflected, refracted and scattered during propagation; for example, the metal material of the stirring rod may reflect the ultrasonic waves at the rod wall, resulting in uneven distribution of ultrasonic energy near and far from the rod wall, which in turn causes inconsistent plant pigment extraction effect, plant cells near the area with strong ultrasonic energy may be over fragmented, and the pigment extraction is sufficient, but may be accompanied by pigment structure damage; while in the area with weak energy, the plant cells are not fully fragmented, the pigment extraction is not complete, which affects the overall extraction efficiency and quality. SUMMARY

[0004] The purpose of the present application is to provide a plant pigment extraction equipment for textile production to solve the problem of uneven distribution of ultrasonic energy in the plant pigment extraction equipment for textile production, which leads to pigment structure damage or incomplete pigment extraction, affecting the overall extraction efficiency and quality.

[0005] To achieve the above purpose, the present application provides the following technical scheme:

[0006] The utility model provides a kind of plant pigment extraction equipment for textile production, including extraction box, ultrasonic transducer and ultrasonic generator, the ultrasonic transducer is sequentially arranged and installed on the upper end of extraction box from bottom to top with ultrasonic generator, and the lower end of the ultrasonic transducer extends to the inside of extraction box, the upper and lower end surfaces of the extraction box are respectively provided with feed inlet and discharge outlet, the coaxial sleeve is provided in the extraction box, the inner wall of the reflux pipe and the top wall and bottom wall of extraction box are combined into resonant cavity, the outer wall of the reflux pipe and the inner wall of extraction box are combined into reflux cavity, the upper and lower ends of the reflux cavity are communicated with resonant cavity, the lower end of the ultrasonic transducer extends into resonant cavity, the output end of the ultrasonic transducer is directed to the bottom surface of extraction box, when ultrasonic wave propagates in liquid, periodic pressure change is generated, in negative pressure stage, micro-bubble is formed in liquid, these bubbles close rapidly in subsequent positive pressure stage, strong impact force is generated when bubble closes, local high temperature and high pressure environment is formed, accompanied by high-speed microjet, its speed can reach hundreds of meters per second, this microjet can stir liquid violently, the liquid boundary layer around plant cell is renewed constantly, promotes solvent and plant cell to contact fully, accelerates plant pigment and other components to diffuse from cell to solvent, meanwhile, under the impetus of microjet, liquid in resonant cavity flows downward and flows upward back to resonant cavity through reflux cavity, avoid uneven distribution of ultrasonic energy in plant pigment extraction equipment for textile production, leading to pigment structure damage or incomplete pigment extraction, affect overall extraction efficiency and quality, ensure the uniformity of ultrasonic wave in plant pigment extraction equipment for textile production, and improve the extraction efficiency of plant pigment extraction equipment for textile production.

[0007] Preferably, the output end is provided with a horn, the horn is in the shape of a circular truncated cone, and the large end of the horn is located at the lower side, the upper and lower ends of the reflux cavity and the resonant cavity are respectively provided with a reflux outlet and a reflux inlet, which is conducive to forming a good fluid circulation path, avoiding the occurrence of dead zones or local uneven flow rate of fluid in the equipment, preventing plant raw materials from not being fully contacted with the extraction solvent during the extraction process due to poor fluid circulation, thereby avoiding the problem of low pigment extraction efficiency, and the horn located at the lower side of the reflux outlet helps to effectively amplify and transmit the ultrasonic energy generated by the ultrasonic transducer into the resonant cavity, the design of the horn can reduce the energy loss during transmission, avoid incomplete pigment extraction due to insufficient energy, ensure the uniformity of ultrasonic wave in the plant pigment extraction equipment for textile production, and improve the extraction efficiency of the plant pigment extraction equipment for textile production.

[0008] Preferably, the lower end of the extraction box is evenly distributed with a plurality of slide bars on the inner wall, a plurality of the slide bars are perpendicular to the lower end of the extraction box, the return pipe is slidably connected to the plurality of slide bars, and the lower end of the extraction box is further rotatably connected to a plurality of adjusting rods, and the plurality of adjusting rods are in threaded connection with the return pipe. By evenly distributing a plurality of slide bars on the inner wall of the lower end of the extraction box, slidably connecting the return pipe to the slide bars, and threadedly connecting a plurality of adjusting rods with the return pipe, the position of the return pipe is accurately adjusted by adjusting the adjusting rods, avoiding uneven liquid backflow in the backflow cavity, preventing local liquid accumulation or unstable flow rate due to poor backflow, and further affecting the consistency of plant pigment extraction, thereby ensuring the consistency of plant pigment extraction in the plant pigment extraction equipment for textile production. At the same time, when the height of the return pipe is adjusted by the adjusting rod, the opening size of the backflow inlet and the backflow outlet will change relatively. When the height of the return pipe is adjusted upward by the adjusting rod, the opening size of the backflow outlet will gradually decrease, while the opening size of the backflow inlet will gradually increase. At this time, the liquid pressure and flow rate of the backflow outlet will gradually increase and impact on the circular truncated cone of the amplitude rod, producing a mixing effect and improving the extraction effect of the plant pigment extraction equipment. At the same time, the above settings can be adjusted for different extraction pressure conditions of plant pigments to achieve better extraction effect.

[0009] Preferably, the inner wall of the backflow cavity is provided with a backflow surface, the backflow surface is corrugated, and the corrugated backflow surfaces on the extraction box and the return pipe are matched with each other. A conventional flat backflow surface will make the extraction liquid flow more smoothly, easily form a boundary layer on the surface of the raw material, hinder the mass transfer process of pigment molecules from the raw material to the extraction liquid, and increase the inner wall surface area of the corrugated backflow surface. The extraction liquid forms more turbulent flow and vortex flow, which can effectively destroy the boundary layer on the surface of the raw material, avoid incomplete pigment extraction caused by low mass transfer efficiency, and prolong the extraction time. At the same time, the turbulent flow and vortex flow make the extraction liquid more fully contact the raw material, which can ensure that the raw material in each part of the equipment can fully act with the extraction liquid, avoid the problem of uneven pigment extraction caused by uneven distribution of extraction liquid and insufficient contact with raw material, improve the stability of product quality, ensure the extraction efficiency of the plant pigment extraction equipment for textile production, and improve the quality of pigment extraction. At the same time, the increased inner wall surface area of the corrugated backflow surface also increases the heat dissipation area of the liquid.

[0010] Preferably, the inner wall of the lower end face of the extraction box is provided with a waveguide table, the waveguide table is conical, the top angle of the waveguide table is equal to 90°, the tip of the waveguide table is upward, the side wall of the waveguide table is provided with a waveguide surface, and the waveguide surface and the backflow inlet are connected through a circular arc surface. The conical waveguide table with the tip upward can guide the ultrasonic wave energy to propagate to the backflow inlet area, reduce the reflection of the energy on the inner wall of the box, avoid the invalid loss of energy, improve the energy utilization rate, and the transition of the waveguide surface and the circular arc surface can make the flow of the extraction liquid from the backflow inlet to the vicinity of the waveguide table more smooth, avoid the problem of poor fluid flow, and ensure the stability of the liquid circulation in the entire extraction system of the textile production plant pigment extraction equipment. At the same time, after the ultrasonic wave contacts the waveguide table, due to the conical design of the waveguide table with the tip upward and the top angle equal to 90°, the angle between the waveguide surface and the bottom surface of the extraction box is 45°. When the ultrasonic wave energy propagates vertically to the lower side wall of the extraction box, the ultrasonic wave energy will be reflected by 90° along the waveguide surface to the backflow inlet area after contacting the waveguide surface, and the ultrasonic wave energy further pushes the liquid in the resonance cavity to flow to the backflow inlet direction.

[0011] Preferably, the backflow cavity is provided with a mixing section and a compression section, the mixing section is located on the lower side of the compression section, and the mixing section and the compression section are conical. The mixing section and the compression section are in communication with the backflow outlet and the backflow inlet. The conical arrangement of the mixing section and the compression section enables the extraction liquid in the backflow cavity to form a complex flow pattern in the mixing section, promotes the mixing of extraction liquids of different regions and different concentrations, avoids the problem of uneven mixing of extraction liquids, and affects the uniformity and consistency of plant pigment extraction. The conical structure of the compression section can compress the backflow extraction liquid to some extent, increase the mixing degree between the plant pigment and the extraction liquid, and ensure the efficiency and quality of pigment extraction in the textile production plant pigment extraction equipment.

[0012] Preferably, the outer side wall of the extraction box is circumferentially provided with a plurality of heat dissipation fins, the vertical direction of the plurality of heat dissipation fins is corrugated, and the outer side wall of the extraction box is coaxially provided with a plurality of pressure-resistant fins. The plurality of pressure-resistant fins are connected with the plurality of heat dissipation fins, and the outer diameter of the plurality of pressure-resistant fins is larger than the outer diameter formed by the plurality of heat dissipation fins. The corrugated heat dissipation fins increase the heat dissipation area, and the corrugated structure can form turbulent flow of air on the surface of the heat dissipation fins, thereby strengthening the heat exchange between the air and the heat dissipation fins, avoiding the problem of excessive temperature in the extraction box due to poor heat dissipation, and affecting the extraction effect of heat-sensitive plant pigments. At the same time, the pressure-resistant fins on the heat dissipation fins enhance the structural strength of the heat dissipation fins and improve their pressure resistance, avoiding damage such as deformation and breakage of the heat dissipation fins due to external force, prolonging the service life of the heat dissipation fins, and ensuring the stability of the heat dissipation components in the textile production plant pigment extraction equipment.

[0013] Preferably, a cleaning groove is coaxially formed on the lower end face of the extraction box. The diameter of the cleaning groove is larger than the diameter of the reflux pipe. The bottom plate of the extraction box and the reflux pipe in the cleaning groove form a quick-release component. The quick-release component is threadedly connected in the cleaning groove. During the extraction of plant pigments, plant residues, pigment deposits and other impurities may remain on the bottom of the extraction box and the reflux pipe. Without a quick-release design, cleaning would require cleaning from the top of the equipment or other narrow openings, which is difficult and makes it hard to completely remove impurities. The quick-release design allows the bottom plate of the extraction box and the reflux pipe to be removed as a whole, facilitating a comprehensive and thorough cleaning of the inside of the cleaning groove and the quick-release component itself. This avoids the problem of impurities remaining due to inconvenient cleaning, which could affect the next extraction effect or cause equipment failure. In addition, with traditional fixed connection methods, when the equipment malfunctions and needs to be repaired or worn parts such as the reflux pipe need to be replaced, it may be necessary to disassemble many parts of the entire equipment, which consumes a lot of time and labor costs. The quick-release component, with its threaded connection, facilitates quick disassembly and installation, reducing the workload and difficulty in the maintenance process and lowering maintenance costs.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention avoids the problem of uneven ultrasonic energy distribution in plant pigment extraction equipment for textile production, which leads to pigment structure damage or incomplete pigment extraction and affects the overall extraction efficiency and quality. This is achieved by coaxially sleeved reflux pipe inside the extraction box, with a resonant cavity inside the reflux pipe and a reflux cavity between the reflux pipe and the inner wall of the extraction box. The output of the ultrasonic transducer is directed towards the bottom surface of the extraction box.

[0016] 2. This invention features multiple sliding rods evenly distributed around the circumference of the inner wall at the lower end of the extraction chamber. The reflux pipe is slidably connected to these sliding rods. Multiple adjusting rods are also rotatably connected to the lower end of the extraction chamber, and all adjusting rods are threadedly connected to the reflux pipe. This avoids uneven liquid reflux in the reflux chamber, prevents localized liquid accumulation or unstable flow rate due to poor reflux, and thus ensures the consistency of plant pigment extraction in textile production plant pigment extraction equipment.

[0017] 3. This invention provides a reflux surface on the inner wall of the reflux chamber. The reflux surface is corrugated, and the peaks and troughs of the corrugated reflux surface on the extraction box and the reflux pipe complement each other. This avoids problems such as incomplete pigment extraction and long extraction time caused by low mass transfer efficiency, as well as uneven pigment extraction caused by uneven distribution of extractant and insufficient contact with raw materials. This ensures the extraction efficiency and quality of plant pigment extraction equipment for textile production. Attached Figure Description

[0024] Please see Figures 1 to 5 This invention provides a plant pigment extraction device for textile production, the technical solution of which is as follows:

[0025] A plant pigment extraction device for textile production includes an extraction box 1, an ultrasonic transducer 2, and an ultrasonic generator 3. The ultrasonic transducer 2 and the ultrasonic generator 3 are arranged sequentially from bottom to top on the upper part of the extraction box 1, with the lower end of the ultrasonic transducer 2 extending into the inner side of the extraction box 1. An inlet 401 and an outlet 402 are respectively provided on the upper and lower end faces of the extraction box 1. A return pipe 501 is coaxially sleeved inside the extraction box 1, and the inner wall of the return pipe 501 is connected to the extraction box 1. The top and bottom walls of the chamber 1 combine to form a resonant cavity 502. The outer wall of the reflux pipe 501 and the inner wall of the extraction chamber 1 combine to form a reflux cavity 503. A reflux surface 508 is provided on the inner wall of the reflux cavity 503. The reflux surface 508 is corrugated, and the crests and troughs of the corrugated reflux surface 508 on the extraction chamber 1 and the reflux pipe 501 are matched with each other. The reflux cavity 503 is also provided with a mixing section 701 and a compression section 702. The mixing section 701 is located below the compression section 702, and the mixing... Section 701 and compression section 702 are arranged in a conical shape. The mixing section 701 and compression section 702 are connected to the reflux outlet 506 and reflux inlet 507, respectively. The lower end of the ultrasonic transducer 2 extends into the resonant cavity 502. An amplitude transformer 505 is installed on the output end 504. The amplitude transformer 505 is frustoconical, and the large end of the amplitude transformer 505 is located on the lower side. The output end 504 of the ultrasonic transducer 2 points to the bottom surface of the extraction box 1. The upper and lower ends of the reflux cavity 503 and the resonant cavity 502 are respectively set as the reflux outlet 506 and reflux inlet 507. The amplitude transformer 505 is located below the reflux outlet 506. This avoids the problem of uneven distribution of ultrasonic energy in the plant pigment extraction equipment for textile production, which leads to damage to the pigment structure or incomplete pigment extraction, affecting the overall extraction efficiency and quality. It ensures the uniformity of ultrasonic waves in the plant pigment extraction equipment for textile production and improves the extraction efficiency of the plant pigment extraction equipment for textile production.

[0026] It is worth noting that a waveguide stage 603 is installed on the inner wall of the lower end face of the extraction box 1. The waveguide stage 603 is conical with its tip pointing upwards. A waveguide surface 604 is provided on the side wall of the waveguide stage 603. The waveguide surface 604 and the return inlet 507 are connected by an arc surface, which avoids ineffective energy loss and improves energy utilization. At the same time, it avoids the problem of poor fluid flow and ensures the stability of liquid circulation in the entire extraction system of the plant pigment extraction equipment for textile production.

[0027] Please see Figures 1 to 5Multiple sliding rods 601 are evenly distributed around the circumference of the lower inner wall of the extraction box 1. The multiple sliding rods 601 are perpendicular to the lower inner wall of the extraction box 1. The reflux pipe 501 is slidably connected to the multiple sliding rods 601. Multiple adjusting rods 602 are also rotatably connected to the lower end of the extraction box 1. The multiple adjusting rods 602 are all threadedly connected to the reflux pipe 501 to avoid uneven liquid reflux in the reflux chamber 503, prevent local liquid accumulation or unstable flow rate due to poor reflux, and thus affect the consistency of plant pigment extraction, ensuring the consistency of plant pigment extraction in the plant pigment extraction equipment for textile production.

[0028] It is worth noting that a cleaning groove 901 is coaxially formed on the lower end face of the extraction box 1. The diameter of the cleaning groove 901 is larger than the diameter of the return pipe 501. The bottom plate of the extraction box 1 inside the cleaning groove 901 and the return pipe 501 form a quick-release component 902. The quick-release component 902 is threadedly connected inside the cleaning groove 901, which avoids the problem of impurities remaining due to inconvenient cleaning, which may affect the extraction effect or cause equipment failure. In addition, with the traditional fixed connection method, when the equipment fails and needs to repair the bottom parts or replace worn parts such as the return pipe 501, it may be necessary to disassemble many parts of the entire equipment, which consumes a lot of time and labor costs. The quick-release component 902 is threadedly connected, which facilitates quick disassembly and installation, reduces the workload and difficulty in the maintenance process, and lowers maintenance costs.

[0029] Please see Figures 1 to 4 Multiple heat dissipation fins 801 are evenly distributed around the outer wall of the extraction box 1. The vertical direction of the multiple heat dissipation fins 801 is corrugated. Multiple anti-compression plates 802 are also coaxially sleeved on the outer wall of the extraction box 1. The multiple anti-compression plates 802 are all connected to the multiple heat dissipation fins 801, and the outer diameter of the multiple anti-compression plates 802 is larger than the outer diameter formed by the multiple heat dissipation fins 801. This avoids the problem of excessive temperature inside the extraction box 1 due to poor heat dissipation, which would affect the extraction effect of heat-sensitive plant pigments. At the same time, the installation of anti-compression plates 802 on the heat dissipation fins 801 enhances the structural strength of the heat dissipation fins 801, improves their compressive strength, avoids the heat dissipation fins 801 from deformation, breakage and other damage due to external forces, extends the service life of the heat dissipation fins 801, and ensures the stability of the heat dissipation components in the plant pigment extraction equipment for textile production.

[0030] When working, please refer to Figures 1 to 5The plant material to be extracted and the extraction solvent are placed into the extraction chamber 1 through the feed inlet 401. After the plant material and extraction solvent completely cover the amplitude transformer 505, the ultrasonic generator 3 is turned on, which drives the ultrasonic transducer 2 to work. The output end 504 of the ultrasonic transducer 2 emits ultrasonic waves downwards, and the ultrasonic energy generated by the ultrasonic transducer 2 is effectively amplified and transmitted to the resonant cavity 502 through the amplitude transformer 505. The ultrasonic waves propagate in the liquid in the resonant cavity 502, generating periodic pressure changes and forming microbubbles. When the bubbles close, they generate strong impact force, local high temperature and high pressure environment, and high-speed microjets. The microjets violently stir the liquid, causing the liquid boundary layer around the plant cells to be constantly renewed, promoting full contact between the solvent and the plant cells, and accelerating the diffusion of plant pigments from the cells into the solvent. Driven by the microjets, the liquid in the resonant cavity 502 flows downwards. After the liquid in the resonant cavity 502 flows downwards and comes into contact with the waveguide 603, it flows along the waveguide surface 604 of the waveguide 603. Due to the connection between the waveguide surface 604 and the return inlet 507... The transition is facilitated by a curved surface, allowing the liquid to flow smoothly from near the waveguide 603 to the return inlet 507. Simultaneously, after the ultrasonic wave contacts the waveguide 603, its conical shape with the tip pointing upwards guides the ultrasonic energy towards the return inlet 507 region, further propelling the liquid within the resonant cavity 502 towards the return inlet 507. At this point, the liquid is pushed into the return cavity 503 and flows upwards, returning to the resonant cavity 502 via the return outlet 506, forming a circulation. During the reflux process, the liquid undergoes different flow patterns in the mixing section 701 and the compression section 702 within the reflux chamber 503. The mixing section 701 promotes thorough mixing of extracts of different regions and concentrations, while the compression section 702 compresses the refluxed extract, increasing the mixing degree between the plant pigments and the extract. After a period of ultrasonic extraction and liquid circulation, the plant pigments are fully dissolved in the extraction solvent, forming an extract containing plant pigments. Finally, the extract is discharged from the outlet 402, completing the extraction process of plant pigments.

[0031] It is worth noting that by evenly distributing multiple sliding rods 601 around the inner circumference of the lower end of the extraction chamber 1, and slidably connecting the reflux pipe 501 to the sliding rods 601, while simultaneously threading multiple adjusting rods 602 to the reflux pipe 501, precise adjustment of the position of the reflux pipe 501 can be achieved. This avoids uneven liquid reflux in the reflux chamber 503, prevents local liquid accumulation or unstable flow rate due to poor reflux, and thus affects the consistency of plant pigment extraction, ensuring the consistency of plant pigment extraction in the plant pigment extraction equipment for textile production.

[0032] It is also worth noting that during the operation of the plant pigment extraction equipment for textile production, the local high temperature generated by the ultrasonic waves acting on the extraction liquid is diverted into the air by the corrugated heat dissipation fins 801 when it flows through the reflux chamber 503. This avoids the problem of excessively high temperature inside the extraction chamber 1 due to poor heat dissipation, which would affect the extraction effect of heat-sensitive plant pigments.

[0033] After extraction, the quick-release piece 902, which consists of the bottom plate of the extraction box 1 and the return pipe 501, can be removed from the cleaning tank 901 by threaded connection. The inside of the cleaning tank 901 and the quick-release piece 902 itself can be thoroughly cleaned to remove residual plant residues, pigment deposits and other impurities for the next use.

[0034] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
